hahahahaha

hero · Answer

That method only works for 3 x 3 matrices bro.

anonymous · Answer

why can't there be more zero's in that matrix haha

hero · Answer

A better approach would be the reduction method.

anonymous · Answer

How does that work?

hero · Answer

You reduce to 4 x 4, then 3 x 3, then 2 x 2, then 1 x 1 and divide by the interior matrix when necessary.

hero · Answer

I can demonstrate it to you.
